Stamp Duty And First‑Home Concessions: State‑By‑State Borrowing Power Guide

Stamp duty and first‑home concessions can change what you can safely borrow by tens of thousands of dollars, but the rules are different in every state and territory. In practice, your address – and whether you qualify as a first‑home buyer – can shift your usable budget more than a 0.25% rate move. This guide shows how the main state regimes work and how to turn the concessions into a concrete price range this week.

Quick answer: Stamp duty is a state tax on property purchases, usually 3–6% of the price. First‑home buyers may get discounts, exemptions or grants that reduce this cost. Because duty is paid from your cash, any saving usually increases your effective deposit and borrowing power, provided you still stay under a safe repayment limit.

Stamp duty comes out of your cash first, directly changing your usable deposit.

1. How stamp duty actually affects your borrowing power

1.1 The simple relationship: more duty = less deposit

For most buyers, stamp duty is paid in cash at or shortly after settlement. Lenders won’t usually add it to the loan (except in some narrow cases with very high equity).

That means:

• Every extra dollar of stamp duty is one less dollar of deposit.
• A lower deposit can:
  • reduce your maximum purchase price, or
  • push your loan‑to‑value ratio (LVR) up into a higher lenders mortgage insurance (LMI) band.

LVR bands matter because lenders and insurers tend to set breakpoints at roughly:

• 80% LVR – usually no LMI
• 80–85% – low LMI
• 85–90% – moderate LMI
• 90–95% – high LMI, tighter policy

A small change in deposit due to stamp duty can tip you over one of those steps.

1.2 Worked example: same income, different state, different outcome

Assume:

• Combined after‑tax income: $140,000
• Safe repayment ceiling at rates 3% higher: 35% of after‑tax income (consistent with our guidance in /insights/understanding-safe-borrowing-limit-first-home-buyers)
• That gives safe repayments of about $4,083 per month.

Indicatively, that might support a loan around $700,000 on principal & interest at a plausible long‑term rate. Now compare:

• State A (no concession) – Stamp duty on a $800,000 property ~4% = $32,000.
• State B (first‑home exemption to $800,000) – Stamp duty = $0.

If you have $120,000 cash savings and want to keep at or below 90% LVR:

• State A

  • Duty: $32,000
  • Other costs (legals, inspections, etc): say $8,000
  • Left for deposit: $80,000
  • To stay at 90% LVR, max price ≈ $800,000 (10% deposit). You’re at the top of duty‑free band but pay full duty.

• State B

  • Duty: $0
  • Other costs: $8,000
  • Left for deposit: $112,000
  • With the same 90% LVR, max price ≈ $1,120,000.

Same income, same savings, but the state concession increases your effective price range by more than $300,000 – on paper. In practice, your serviceability (ability to repay) will likely cap you lower, which is why we always run both serviceability and deposit calculations.

1.3 Don’t let the concession tempt you past safe limits

Our accumulated guidance across multiple articles is consistent: a practical safety ceiling is to keep total home loan repayments under about 30–35% of after‑tax income at rates 3% higher than today (see /insights/understanding-safe-borrowing-limit-first-home-buyers and our guides for higher‑value borrowers).

Concessions increase choice. They don’t remove risk. Use them to:

• reduce your loan size and monthly repayments, or
• build a better buffer, not just chase the maximum contract price.

2. Big picture: how stamp duty and concessions differ by state

Each state and territory sets its own:

1. Stamp duty rate scales
2. First‑home buyer discounts and thresholds
3. Grants for new homes or regional areas
4. Rules on occupancy (e.g. must move in within 12 months, live there 6–12 months)

Rates and thresholds change often. Always check your state revenue office or use a current stamp duty calculator for NSW, VIC, QLD and others. Treat any figures below as indicative only.

2.1 Typical patterns across the country

Broadly:

• NSW and VIC have relatively high duty but meaningful first‑home concessions within certain price bands.
• QLD has lower duty scales, with concessions that heavily favour lower‑priced homes.
• SA, WA and TAS have smaller but still significant concessions.
• ACT and NT run their own versions, with ACT shifting gradually towards broad‑based land tax.

Where you sit relative to your state’s concession threshold is critical.

3. NSW: duty, concessions and borrowing power in practice

While rules change, NSW is a good example of how thresholds and grants interact with borrowing power.

3.1 Typical NSW pattern

• Standard duty of roughly 3–5% on typical first‑home price ranges.
• First‑home buyer duty discounts or exemptions up to a certain purchase price, usually with tighter rules above that.
• Separate federal schemes like FHBG and FHSS that overlay state duty rules (see /insights/using-fhbg-fhss-state-concessions-off-the-plan).

3.2 Example: just below vs just above an NSW concession band

Assume again:

• Cash savings: $120,000
• Borrowing capacity (serviceability‑tested): $700,000

Scenario A – Buy at $800,000 with full first‑home duty concession:

• Duty: $0 (assume full exemption)
• Other costs: $8,000
• Deposit on price: $112,000
• Loan required: $688,000 (LVR 86%)

Scenario B – Buy at $850,000 with reduced or no concession:

• Duty: say ~$25,000 (illustrative)
• Other costs: $8,000
• Left for deposit: $87,000
• To avoid going beyond 90% LVR, you’d need at least ~10% deposit = $85,000. That’s just inside 90% LVR, but now:
  • Loan required: $763,000
  • Repayments increase
  • LMI premium higher

The extra $50,000 on price costs you more than $50,000 in total finance impact because:

1. You pay duty in cash.
2. You borrow more at a higher LVR band.

That’s why in NSW you often see buyers target the top of the concession band or jump well above it – not hover just over where you lose the benefit but still pay big duty.

3.3 NSW, off‑the‑plan and timing

With off‑the‑plan in NSW (and elsewhere), the key dates are:

• Contract date – often controls eligibility for grants and duty concessions.
• Settlement date – when duty is payable and loan funds are drawn.

If your income or situation may change before settlement, pair this guide with /insights/locking-in-finance-income-change-before-off-the-plan-settlement so you don’t rely on concessions you ultimately can’t use due to a serviceability issue at settlement.
